Question

A. y= 1/2x-14
B. y=1/2x-5
C. y=2x-14
D. y=2x-5

Answer 1

B. y=1/2x-5

Explanation:

From the graph, we read the slope of line JK.

slope = rise/run = -3/-6 = 1/2

The equation we need has the same slope.

y = mx + b

y = (1/2)x + b

It passes through point P(6, -2). Now we find b.

-2 = (1/2)(6) + b

-2 = 3 + b

b = -5

The equation is

y = (1/2)x - 5
